Considering the examples of a molecular dimer and a carbon nanotube double quantum dot, we here theoretically investigate transport through a two-site system that is strongly coupled to a single vibrational mode. Using a quantum master equation approach, we demonstrate that, depending on the relative positions of the two dots, electron-phonon interactions can lead to ... 14:00 - 15:00 Weekly Seminar Coherence of Coupled Dangling-Bond Pairs on a Silicon Surface School NANO SCIENCES Coherence of Coupled Dangling-Bond Pairs on a Silicon Surface Abstract: Dangling bonds on semiconductor surfaces are known as truly atomic-scale quantum dots. In recent years, experiments have shown that dangling bonds located close enough to each other display coupling behavior. In this presentation, we characterize coherence and coupling strength of dangling-bond pairs that are sharing an excess electron and are located on the phosphorous-doped hydrogen-terminated silicon(100)-2x1 surface. We employ ab-initio time-dependent density functional theory technique to investigate the tunneling rate for various dangling-bond pair ... 15:00 - 16:00 Weekly Seminar Systems Neuroscience: New Approaches to Old Questions School PARTICLES AND ACCELERATORS Our research principally involves studying the activity of single neurons, and large populations of neurons in sensory and motor structures within the brain. We are interested in developing and implementing electrophysiological methods in fundamental problems of systems and circuit-level neuroscience. To this end, we are conducting parallel behavioral and physiological experiments in human and animals that are trained to perform selected cognitive tasks. By recording the activity of cortical neurons during performance of such tasks, we gain insights into the relationship of neuronal activity and animal’s behavior. A mixture of electrophysiolo ... |
